    Which of the following organometallic compound has \[\sigma \] and \[\pi \] bond?                 [AIPMT 2001]

    A) \[[Fe({{\eta }^{5}}-{{C}_{5}}{{H}_{5}}){{ & }_{2}}]\]          

    B) \[K[PtC{{l}_{3}}({{\eta }^{2}}-{{C}_{2}}{{H}_{4}})]\]

    C) \[{{[Co{{(CO)}_{5}}N{{H}_{3}}]}^{2+}}\]   

    D) \[Fe{{(C{{H}_{3}})}_{3}}\]

    Correct Answer: C

    Solution :

    [c] \[{{[Co{{(CO)}_{5}}N{{H}_{3}}]}^{2+}}\]. In this complex, Co-atom attached with \[N{{H}_{3}}\] through \[\sigma \] bonding and with CO attached with dative \[\pi \]-bond.
